Recombinant Rat IL-4 Protein (CHO, C-His) 别名：Interleukin-4; BCGF-1; B cell stimulatory factor-1; 重组大鼠IL-4蛋白 (CHO, C-His)
Interleukin-4 (IL-4) is a pleiotropic cytokine regulates diverse T and B cell responses including cell proliferation, survival, and gene expression. IL-4 regulates the differentiation of native CD4+ T cells (Th0 cells) into helper Th2 cells, and regulates the immunoglobulin class switching to the IgG1 and IgE isotypes.

生物活性
Interleukin-4 (IL-4) is a pleiotropic cytokine regulates diverse T and B cell responses including cell proliferation, survival, and gene expression. IL-4 regulates the differentiation of native CD4+ T cells (Th0 cells) into helper Th2 cells, and regulates the immunoglobulin class switching to the IgG1 and IgE isotypes. Interleukin-4 is produced by mast cells, T cells, and bone marrow stromal cells. It is a key regulator in hormone control and adaptive immunity. IL-4 also plays a major role in inflammation response and wound repair via activation of macrophage into M2 cells.
Measured in a proliferationassay using C6 cells, the ED50 is < 0.2 μg/ml.
Accession: P20096
Apparent Molecular Weight: 18~22 kDa, reducing conditions
Endotoxin < 0.2 EU/μg
Lyophilized after extensive dialysis against PBS.
实验参考
建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中，输入您的动物实验相关数据并点击计算，即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg，平均每只动物的体重为20 g，每只动物的给药体积是100 μL，动物数量为20只，则该动物实验的总需药量为4 mg，工作液终浓度为2 mg/mL。
1：鉴于实验过程的损耗，建议您至少多配1-2只动物的量；
2：为该产品最终给药时的浓度。
